Reference Letter - 2 designations with same job duties

[adnan.mohammed]

I got promoted and therefore have two designations, but with same job duties. Post promotion I supervised people under me for the same duties that I did. In my company letter head they have mentioned my last designation for the entire tenure, that's how the practice is here.
What do I do now? If I were to ask my company again to for the reference letter with the changes, should I club both designations into 1 letter? Would it raise any more questions? Or should I simply proceed with the letter that I have?

I had the same situation. I added a second line in the letter, basically saying:

From xx/xx/xxxx onwards: promoted to Senior YYY
Duties: similar to previous duties plus supervision of XYZ personnel

If your salary changed (I hope for you), keep in mind that this also should be reflected.
